A cooling tower, a metalworking fluid sump, and a boiler feedwater line all have the same underlying question: how many bacteria are in there right now, and does someone need...

Dipslides
Bacteria Counts Without Sending Samples to a Lab
Dipslides are dual-media agar paddles sealed inside a tube — dip the paddle in the sample, reseal, incubate, and compare the colony growth against a printed reference chart to get a semi-quantitative CFU/mL count. Five paddle variants cover aerobic bacteria, E. coli and coliform, Staphylococcus aureus, and yeasts and moulds on two different agar bases. A sixth format — the SRB Test tube — targets anaerobic sulphate-reducing bacteria, which dipslides can't reach, using a 0-5 day incubation with no refrigeration required. Results can be logged and tracked digitally through the uPyxis mobile app, giving a paper-free record for cooling towers, drinking water systems, pools, food, cosmetics, pharmaceutical and hospital hygiene programmes.
No lab required — semi-quantitative CFU/mL results read directly on-site against a printed comparison chart
Aerobic and anaerobic coverage — dipslide paddles for aerobic organisms, plus a dedicated SRB test tube for anaerobic sulphate-reducers
Fast turnaround — results in as little as 18-24 hours for bacteria, 3-5 days for yeasts, moulds and SRB
uPyxis app logging — optional mobile app for digitally recording and tracking dipslide readings over time

All Dipslides
Aerobic Bacteria
Pyxis Dipslide AB-T
Detection: 10² – 10⁷ CFU/mL
Total aerobic bacteria count via TTC paddle. Results in 18-24h at 35°C, or 48-96h at room temperature. Used across drinking water, cooling water, pools, pharma and hospital hygiene.
E. Coli & Coliform
Pyxis Dipslide EC-C
Detection: 10² – 10⁶ CFU/mL
Chromogenic paddle for E. coli and coliform bacteria — key indicators of drinking water contamination and food safety risk. Results in 18-24h incubation.
Staphylococcus Aureus
Pyxis Dipslide SA-C
35°C Constant Temperature Incubation
Chromogenic paddle for rapid Staph aureus detection — biological safety of drinking water and hygiene monitoring for food and cosmetics production.
Yeasts & Moulds — Malt
Pyxis Dipslide YM-M
Yeasts 10²–10⁶ CFU/mL · Moulds "+" to "+++"
Malt agar paddle for total yeast and mould counts. Incubate 25-30°C for 3-5 days, or 5-6 days at room temperature. Flags early fungal contamination in HVAC and damp areas.
Yeasts & Moulds — Rose
Pyxis Dipslide YM-R
Yeasts 10²–10⁶ CFU/mL · Moulds "+" to "+++"
Rose bengal agar paddle for total yeast and mould counts, with colour differentiation between fungal colonies. Widely used in cosmetics and food production.
Sulphate-Reducing Bacteria
Pyxis SRB-Test Kit
0-5 Day Incubation at 35°C · No Refrigeration
Ready-to-use anaerobic test tube — not a dipslide paddle — for sulphate-reducing bacteria that drive microbially-influenced corrosion in industrial water systems and piping.
